Mazda CX-5 electrical problems

smart key. during driving all the lights on the dashboard come on and the siren goes off and unable to have it turn off. After a period of time, its wears down the battery and it is no longer drivable. First time, it was towed to the AAA auto repair and they could not find anything wrong with it. The 2nd and 3rd time, AAA towed it back to Maita Mazda where we purchased it in good faith less than two months ago, and their service department could not find anything wrong with the electrical system. They replaced the battery the seond time, and the issue still occurred again when I turned it off. Then turned it back on as I needed to close the driver side window, and it would not turn on. No one seems to believe me, and we cannot get Maita to take it back and give us another vehicle in its place. It is extemely dangerous to drive in traffic, and we only bought it because it has a big enough trunk for my spouse's walker, and later a wheel chair. It is paid for in full,

Last month, my vehicle suddenly applied the electronic parking brake (EPB) while I was driving. The EPB & related warning lights illuminated & would not release until the vehicle was turned off. After turning off the vehicle, the EPB motor could be heard applying the brake to the rear wheels. When the car was restarted, the EPB would remain off for a period of time but would then suddenly reapply. I took my vehicle to a Mazda dealer & they determined the calipers & EPB motor had failed due to my vehicle not being placed in service mode by the brake servicer. This explanation makes no sense because the brakes were replaced over a year ago (& not since) with thousands of miles being driven since then without this issue arising. I also conducted my own research & found that Mazda has issued at least 3 separate technical service bulletins (TSB) on this issue. The first two recommended replacement of the EPB switch & the third determined that defective calipers were the cause and should be replaced. I asked the dealer to save my calipers & confirmed that they are part of the defective batch noted in this TSB. I have contacted Mazda (including their legal counsel) & they are unwilling to provide any explanation or engage in any sort of investigation. As former legal counsel for an automotive company, I believe this presents a serious safety issue for consumers based upon the fact that a parking brake could randomly engage while driving & cause sudden loss of speed/control. Thankfully, this did not result in harm to my family, myself or others. I am certain that this issue is affecting others based on chatboard discussions I have found online related to this topic (which helped me find the TSB). I am concerned that Mazda may have attempted to undertake a silent recall via this TSB where in warranty customers are covered & out of warranty customers are given the 'service mode' explanation to justify their responsibility. This should have been handled as a recall by Mazda.

The Mazda infotainment system has a problem that is known to the manufacturer and many vehicle owners. It is called "ghost touch" where the touch screen malfunctions and registers an input that is not actually made. The touch screen is not touched, but the infotainment system still reacts and changes inputs, adjusts volume, and performs other actions. This has been a major safety risk for me and my family on several occasions. On several occasions, the infotainment system will be set at a reasonable volume playing music or a radio station or sometimes even off or muted. The "ghost touch" occurred and changed the volume input of the navigation system (which was not being used) to the MAXIMUM level. The car then announces that "navigation will be at this volume." The voice is extremely loud and is completely unexpected. This stated the driver and has almost caused accidents on at least three occasions. It is the equivalent of someone blasting an airhorn in your ear while you are driving. It is shocking and can cause accidents. This problem is known to the dealer and manufacturer. I have taken the vehicle for service of this issue as recently as August 23, 2022. The dealer knows the issue happens with many of its vehicles. They refuse to fix the issue in my car without charging me extraordinary amounts of money because it is out of the full warranty. The car has 44,000 miles and is a 2018 model purchased new in February 2018. They are aware that it is a critical safety issue, but they will not fix it. They have issued a recall for the same issue on another vehicle, but not on mine. This malfunction happens without warning. Again, the dealer and manufacturer are well aware of the issue, but they refuse to fix it even though it is a critical safety issue and it is covered under the implied warranty of the vehicle.

I bought a 2021 Mazda CX-5 from Ramsey Mazda of Des Moines, IA. It offered comparable comfort & features. A selling point was the safety features touted by the salesman. Odd things occurred during the first few months but I attributed it to a learning curve. I saw some odd messages but I really did not think it was relevant until June 28, 2022. I was backing out from a parking space. The Blind Spot Monitoring failed to indicate a car approaching from the right that then stopped in my blind spot. I hit the car behind me. Despite the fact, I understand personal responsibility, I never would have had the BSM worked correctly. I dropped the car off on July 15, 2022 to the Ramsey Mazda Service Center after the BSM failure and a Check Engine Light appeared. I already had the Ramsey Mazda Collision Center look at the car and told them of the of the BSM failure. That man doing the estimate said he had heard of those failures before. On July 15, I dropped the car off at the Ramsey Mazda Service Center to look at the BSM, a Check Engine light, the door locks and the hatch opening on its own. I tried to tell the Service Center that there was something severely wrong with the electrical system in this vehicle. I have a witness to its erratic behavior, but I was continually dismissed. There is more wrong now with my car than when I left it with the dealership. They kept my car for 19 days. During the 19 days, I continually had to call and check on the status of my vehicle. Ramsey Mazda was not and is still not initiating conversation with me or responding to voicemails. The manager of the Ramsey Mazda Dealership on Hickman in Des Moines, IA (JD) is supposed to be handling this issue personally with Mazda Corporate because it now “appears” to be affecting multiple systems in his words. Multiple issues include but are not limited to the BSM, Seat Belt notifications, power driver’s seat, camera system, cruise control system, entertainment system, & hands free communications.

I have had a system malfunction, that has caused a dead battery in May 2022 and then again Aug 2022. The car was in park and I received a notification on the Mazda app about 5 hours after being in the car that stated "Critical Vehicle Malfunction Alert." I had to have my car towed and serviced at a Mazda dealer but they found no issue with the battery. This happened again in August. According to the Mazda C-X5 Manual, like all modern cars, even if something was left on (light on, door open, ACC on) it should automatically turn off after 25 minutes.

Parked by the curb at the Ft. Lauderdale International Airport. I put the car in Park and left the car idling with the air-conditioning running.as it was 95 degrees and about 100 at around 8:00 AM. There was a shuttle van parked by the curb about 11 feet in front of me. I had to exit my car to talk to the driver in the car behind me. I walked to the car behind me and started talking to the driver. I glanced back at my Mazda CX5 and it started rolling forward. I ran up to the car and got the door open and stepped on the brake. The brakes did not engage. I repeated stepping on the brake several times and the car would not stop. I got in the drivers seat to shift the car into reverse and keep my foot on the brake pedal. The car would not shift into reverse. and by this time the Mazda had pinned to the shuttle van a lady who was trying to unload her luggage. On the sixth attempt to shift into reverse the shifter finally moved into reverse and by standers came to the aid of the lady that had been pinned to the shuttle van. Airport security and the Broward County police took the statements. The lady retrieving her baggage declined medical attention. When I checked to see what the police were reporting they did not acknowledge that I was attempting to stop a runaway vehicle. The report said that I failed to put the car in park and left it in drive. It is not possible to get out of a car that is idling and in gear without the car moving forward or backward before you can even get all the way out of the car. This incident happened about mid July in 2017. Near the end of June this year while in my driveway I left the car idling and in park, exited the car walking to the rear of the car and it dropped into reverse. Got back in the car and shut off the engine. July 2017 the local Mazda dealer inspected the vehicle and could not find as problem. Not unlikely with an intermittent electrical anomaly. There were no prior warning lamps in either incident.

The navigation display turns fails / turns off and on throughout the drive. It turns on then goes off while backing out with the rearview camera in use. It goes off during drives, while directions are in use, while calls are in session, and with no active use at all. After checking online I found that numerous Mazda owners experience the same with thief CX5-s but there is no collective effort by Mazda to find a solution. I paid for extended warranty with Navigation Display covered and they still cannot find a solution. This is more than inconvenience. It is a serious safety issue when physical distraction is caused by manufacturer defect which can lead to accidents on the highway at high speeds relying on the navigation, while backing up viewing the camera, while driving on windy roads and the screen goes out. The auto response for most drivers is to try and reach for the phone to continue directions, stop abruptly if backing up and the screen goes out, reach for the phone to take it off blue tooth so the hands free conversation is not dropped. It is not to much to expect a major auto manufacturer to have a stable navigation screen. The local dealerships do not take it seriously. How can this matter be escalated as a matter of safety?
